Creating your Healthy Frozen Yogurt-Oat Bars with Blueberry Swirl is easy! Follow these steps:

1. Prepare Your Pan: Line an 8×8 inch baking dish with parchment paper for easy removal.
2. Combine Oats and Yogurt: In a medium bowl, mix the rolled oats, Greek yogurt, honey or maple syrup, vanilla extract, and salt until well combined.
3. Spread the Mixture: Transfer the oat-yogurt mixture into the prepared baking dish. Press it down evenly to create a flat layer.
4. Make the Blueberry Swirl: In a small bowl, mash the blueberries with lemon juice until you achieve a slightly chunky consistency.
5. Add Swirl: Drop spoonfuls of the mashed blueberry mixture over the oat layer. Use a knife or spatula to swirl it through lightly.
6. Freeze: Place the baking dish in the freezer for about 4 hours or until the mixture is fully set.
7. Cut into Bars: Once frozen, remove the mixture from the dish by lifting the parchment paper. Cut into squares or bars.
8. Store: Keep any extra bars in an airtight container in the freezer for up to a month.

These steps will guide you perfectly in creating these delightful bars without a hitch!
